Convert Map to JSON object in Javascript

Question

So Ive got the following javascript which contains a key/value pair to map a nested path to a directory.

function createPaths(aliases, propName, path) {
             


        

Answer 1

just using ES6 ways

1. Object.fromEntries

const log = console.log;

const map = new Map();
// undefined
map.set(`a`, 1);
// Map(1) {"a" => 1}
map.set(`b`, 2);
// Map(1) {"a" => 1, "b" => 2}
map.set(`c`, 3);
// Map(2) {"a" => 1, "b" => 2, "c" => 3}

// Object.fromEntries ✅
const obj = Object.fromEntries(map);

log(`\nobj`, obj);
// obj { a: 1, b: 2, c: 3 }

2. ...spread & destructuring assignment

const log = console.log;

const map = new Map();
// undefined
map.set(`a`, 1);
// Map(1) {"a" => 1}
map.set(`b`, 2);
// Map(1) {"a" => 1, "b" => 2}
map.set(`c`, 3);
// Map(2) {"a" => 1, "b" => 2, "c" => 3}

const autoConvertMapToObject = (map) => {
  const obj = {};
  for (const item of [...map]) {
    const [
      key,
      value
    ] = item;
    obj[key] = value;
  }
  return obj;
}

const obj = autoConvertMapToObject(map)

log(`\nobj`, obj);
// obj { a: 1, b: 2, c: 3 }
